摘要
Abstract
The high cost of offshore oil test and gas well test demands a shorter test time ,making the well-test curve of low permeability reservoir incomplete ,and calculation of the reservoir permeability inaccurate .Through deconvolution testing technique based on Duhamel Superposition Principle ,the production test section and the production pressure history of the test section before the short build -up test are superposed to the short build-up test .A short time build-up test is turned into a long time constant output drawdown test .Therefore ,the radial flow of well test curves can be explained ,and the test time is equivalent to a substantial increase in build -up test .The reservoir per-meability can be accurately interpreted ,and the reservoir physical properties can be evaluated accurately .In order to provide guidance for the development of low permeability oil and gas field ,the successful technique of deconvolution test should be used in the low permeability oil and gas well of M gas field and N oil field .关键词
